Leak detection service
Find a hidden water leak fast, without tearing your home apart. Non-invasive thermal, acoustic and tracer-gas detection across Cornwall, with an insurance-approved report.
A hidden water leak can run for weeks behind a wall, under a floor or beneath the garden before you ever see a stain. All the while it pushes up your water bill and damages the building. By the time damp shows on the surface, the leak is often somewhere else entirely.
Cornwall Leak Detection Specialists locate the exact source of hidden water leaks in homes and businesses across Cornwall using non-invasive equipment, so we pinpoint the problem before any tiles, plaster or concrete come up. You get a clear answer, minimal disruption and an insurance-approved report to help you claim the cost back. If you want to understand the warning signs first, our water leak guide walks you through them.
Common signs you have a hidden water leak: an unexplained jump in your water bill, the sound of running water with everything off, damp or warm patches on floors or walls, reduced water pressure, a constantly cycling boiler, or mould and a musty smell.

A water leak almost never fixes itself. Every day it runs, it adds to your bill and works deeper into the fabric of your home. Catch it early and the repair is usually small and local. Leave it, and the costs climb.
Left unchecked, a hidden water leak can:
✓keep pushing your water bill higher month after month✓rot floor timbers, soak insulation and ruin plaster✓lead to black mould and the musty smell that comes with it✓spread well beyond the original leak, turning a small fix into a major one
The sooner it is found, the less damage it does and the easier it is to put right. We pinpoint the exact source quickly and give you a clear, insurance-ready report.
Our method
No guesswork and no unnecessary digging. We combine several detection methods to confirm the exact location before any access work begins:
Thermal imaging spots the temperature differences where water is escaping behind surfaces
Acoustic listening uses ground microphones and correlators to pick up the sound of water escaping a pipe
Tracer gas: a safe gas goes into the pipe and we detect it where it surfaces, which pinpoints the leak
Moisture mapping: meters trace the spread of moisture back to its source
Local to Cornwall, not a franchise from up country
Non-invasive first, so we protect your floors, walls and garden
